Crypt::util provides an easy, intuitive and forgiving api for wielding crypto-fu.

the api is designed as a cascade, with rich features built using simpler ones. this means that the option processing is uniform throughout, and the behaviors are generally predictable.

note that crypt::util doesn't do any crypto on its own, but delegates the actual work to the various other crypto modules on the cpan. crypt::util merely wraps these modules, providing uniform parameters, and building on top of their polymorphism with higher level features.
